STORM-TYPE SHINGLE CLAMP.

Application filed October 20, 1925. Serial No. 63,700.

To all whom it may concern.

Be it known that I, J osnrn C.BARLEY, a citizen of the United States,residing at York, in the county of York and State of Pennsylvania, have'invented new and useful Improvements in Storm-Type Shingle Clamps, ofwhich the following is a"specification. v I

This invention relates to shingle clamps for roofing shingles of thatparticular kind which are made by combining a congealing material with afibrous or mineral material.

The object of this invention is to provide a shingle clamp which willembed itself into the shingle in such a manner that it will not slipoff, and in this manner obviate the use of nails or other form offasteners which require the particular attention of-the inc-- chanic foradaptation. Another object is to provide a snow catcher in a shingleclamp having the above characteristics.

Other objects will beapparent and this invention will be more fullyunderstood from the following description, taken in connection with theaccompanying drawing, forming a part hereof, and in which similarnumerals refer to similarparts throughout the several views.

Fig. l-represents an elevation of one form of my shingle clamp.

Fig. 2 is a lan View of Fig. 1. I

Fig. 3 represents a group of shingles arranged in the usual manner andone form of my shingle clamp, that shown in-F ig. 1, attached thereto. 7

Fig. 4 is a sectional view of Fig. 3 taken on line 4-4, the same beingsomewhat enlar'g'ed, the shingles being shown in sectional view, and theclamp in full elevation.

Fig. 5 represents an elevation of a modified form of my shingle clamp.

With reference to the drawing :-The clamp as shown is formed of wirehaving a return bend at 6, theends 7 thereof extending downward and arebent at right angle at the points 8 in opposite directions to form thehorizontal sections 9; these horizontal sections 9 are also bent atright angle at the point 10 to form the vertical sections 11; andfurther, these vertical sections 11 are bent at right angle at the point12 to form the claw ends and snow catchers 14. These claw ends or snowcatchers as here shown comprise merely a wire loop 15; however it willbe apparent to those 5 illed in the art that these loops 15 might bemodified, for

instance, to better suit manufacturin con-' ditions, without sacrificingany of t e inventive features herein disclosed. However to fulfill theobjects of this invention, it is essential that claws of some characterare provided at 16, and that obstructions of an effective nature forholding the snow are provided at 18. I prefer to provide. a claw19-also, at the return bend 6 of such character which will readily embeditself in the under side of the shingle.

The manner in which this clam grips the shingles is well represented in*i'g. 4; 20 and 21 being the two shingles which are clamped and therebyheld against separation; and 23 represents the shank end of the shingle24, of Fig. 3. Normally. the clamp tends to assume a straight line asshown in Fig. 2, but the resiliency of the wire renders it capable ofbeing sprung over the edges of two shingles, and then the various prongs7 and 11 take the positions shown in Fig. 4.

Although the claws 16 and 19 as represented in the drawing are slightlydifferent, in that the claw 19 is shown to be sharp, while the claw 16has a more rounded end, nevertheless they are the same so far as theirmanners of gripping the shingles are concerned. Obviously in either caseeach claw must be sufficiently sharp so that it will embed itself in theshingle material, throu h the normal pressure efi'ected by theresiliency of the wire in endeavoring to assume its normal position asshown most clearly in Fig. 2. i

It should be understood that this clamp is primarily designed to be usedin connection with shingles of the soft congealing character, that is tosay, shingles which will become soft from the heat of the sun. Withreference to Fig. 4, the surface of shingle 20 Where the claw 16 islocated is exposed directly to the suns rays, while the surface ofshingle 21 where the claw 19 is located is not so exposed, therefore theclaw 16 need not, or should not be as sharp as the claw 19. Of courseafter a certain time the shingles usually get soft enough from the heatof the sun so that the prongs 11 and 7 will also embed at leastpartially in the shin le material. This condition is most desira le butnot essential, but at any rate the clamp must be sufliciently yieldingso that the until it can readily he slipped in place. The

prongs are then released to snap against the "shingle surfaces; It maythen require some time for the claws to embed in the shingle "material,this depends upon the softness of the shingle material, or in otherwords its temperature.

After the clamp is sprung on the shingles, the normal reaction of thewire tendin to move the prongs 7 and 11 in the directions indicated bythe arrows 25 and 26, respectively, cause the claws 16 and 19 to embedin the shingles as shown. These claws prevent the clamp from slippingoil in the direction indicated by arrow 27, even against the effect ofany-snow whichmight tend to slide off the roof in this direction; theloops 15 of course-forms an obstruction to prevent the snow fromsliding.

- The modified formsliown in Fig. 5, is substantially'the same kind ofclamp as that shown inFig. 1; the various portions thereof which aresubstantially the same are indicated by like numerals. The shingles aresometimes divided at the very point where this'clamp should be placed,for instance, as represented by dotted line 28; and when the prongs 7are'close as shown in Fig. 1-, there is a possibility that they mightget between the shingle units; for this reason the'form shown in Fig. 5has some advantage.

Having thus described my invention,

what I claim and desire to secure by Letters Patent is as follows l. Ashingle clamp comprising front and rear prongs, a claw on the upper endof the rear prong and suitably arranged to hook into the shingle whichis being clamped, and a combination claw and snow obstructing device onthe upper end of the front prong.

2. A shingle clamp comprising resilient front and rear prongs, acombination claw and snow obstructing device on the upper end of saidfront prong, said claw being suitably arranged to hook into the shinglethrough the resilient action of said prongs,-

3. A shingle clamp comprising resilient front and rear prongs, saidprongs being suitably arranged to embed in the shingle material throughthe inherent resiliency of said prongs.

4. A shingle clamp formed of wire, comprising prongs extending downward,lateral sections extending in opposite directions at right angle to saidprongs, additional prongs extending vertically from said lateralsections. and loops formed on the ends of said additional prongs andarranged to serve as an obstruction to slidable snow.

5. A shingle clamp comprising resilient front and rear prongs, a claw onthe upper end of the rear prong, said claw bein suitably arranged tohook into the s in'gle through the resilient action of said prongs.

In testimony whereof I ailix my signature.
